But anyways, Oliver turned 21 on January 17th! I just know that Cooper gave him his first legal drink, probably something fruity đ, and they probably went to Vegas. They ended up losing like 10k at the casino (Cooper knows how to play all the card games, while Oliver loves the slot machines) got a little (a lot, totally blasted) drunk and decided to get married, Cooperâs idea of course. They didnât though, they were too drunk to even make it out of their hotel. They woke up the next day with a hangover. They didnât remember anything till they both saw the ring on Oliverâs finger. The shock and embarrassment was shortly lived though, because Cooper also noticed his foot was hurting. It turned out to be a fractured toe, they canât remember how it happened.
